11 Claims.

This invention relates to door hinge locating and marking gauges and more particularly to? gauge of this nature having in its structure means whereby the width length and thickness of the cuts in a door and in a door frame to reoeive the hinge flaps may be accurately and conveniently marked.

When hanging a door in a door frame, the door is first fitted to the opening in the frame, after which the location of the hinges is ascertained and marked on the door and on the door frame. Considerable time is consumed and labor is expended in locating the cuts in which the hinge flaps are to'be seated in both the door and the door frame when the usual carpenters scale, squares, thickness gauges, and straight edges are used. Even when care is used in making measurements inaccuracies occur which are apt to require replacement of material, or patching at the cuts.

To avoidthe above disadvantages and tolocate the cuts for the hinge flaps required in both the door and door frame expeditiously and without the necessity of a plurality of measurements it is contemplated as objects of this invention to provide a gauge whereby, when the door is once fittedto the frame, the frame and door may be marked simultaneously to show the'desired location of thehinges, and thento mark the door and door frame, after separating them for the correct location of the hinge flaps on both the door and door frame and to mark the'door and door frame for the correct length, width and depth of the cut to receive the hinge flaps, by the use of'the same gauge.

Another object is to provide ahingelocating and marking gauge of the above nature on one piece of-material, and of such form that itmay .be conveniently carriedin the pocket of the user's work-clothing.

A further object is to provide a door hinge locating and marking gauge which w-illbe relatively inexpensive to manufacture, simple in con-- struction, practical and very efficient, accurate, and durable in use.

With theseand other objects in view, which will appear as the description proceeds; there has been illustrated in the accompanying drawings one form in which the invention maybe embodied in practice.

Referring now to the drawings wherein like reference numerals designate'li ke' parts throughout the several views, the referencenumeral ll denotesa door frameand the" reference numeral 12 denotes a door, shown in Figure l as fitted together ready to have hinges applied thereto. A hinge locatingand marking gauge embodying the principles and features of this invention is shown at i3 positioned inrespect to the door [2 and frame H to locate and mark them-by nicks, or indentations, as indicated at M; Figure 1.

The hinge locating and marking gauge [3 of this invention is preferably made of sheetmetal and is generally irrthe form of' a flat plate having a body portion [5 presenting-a thin front edge IS; A short flange l'lis provided on each side edge l8-and I 9 ofthe platebody portion I5. The flanges l'l are spacedinwardly from the front edge I6 and extend fromthe top surface of the portion I 5 substantially at right angles thereto. The front end-2i of the flanges I1 is inclined upwardly and rearwardly and preferably is sharpened. Aflange 22" is provided: on each side edge [8 and IQ of theplateportion' I151 The flanges- 22 are spacedinwardlyfrom the front edge 16, an amount equal to thespacing of the and extends across the body portion l5 at right angles to the edges 18 and IS.

The width of the body portion l5 from edge Hi to the side edge I9 is substantially equal to the length of the flaps of a butt hingeto be" applied to the door [2 and door frame H.

by locating the gauge the desired amount fromv the top and bottom of the door l2 previously fitted to the frame, and inserting the thin edge betweenthe door edge and the adjacent-edge of the door frame, as indicated in Figure 1, and then pressing the gauge toward the door, the sharpened front end edges of the flanges Hand 22 will mark the extent of the length of the hinge flap simultaneously on both the door and the door frame by making the nicks it, Figure 1.

After marking the door l2 and frame H by nicks, or indentations 14, the door i2 is removed from the frame H and positioned to present its hinge edge as in Figure 2.. The gauge i3 is then laid upon this door edge 25 with the shoulder 24 engaged against the front, or back, surface of the door and the flanges 22 engaged against the surface of the door hinge edge 25 at the nicks l4. By using the flanges 22 as guides, lines 25 may be scribed across the door edge 25, see Figures 2 and 3, by any pointed member;

The amount the hinge flap is set in from the front surface of the door is next gauged and marked, see Figures 4 and 5. A flange 2i, extending inwardly from the rear edge 28 of the body portion l5 and parallel with the side edge I8, is adapted to be engaged against the rear surface of the door. The flange 21 is spaced away from the edge 18 the proper amount to cause the sharpened edge of a lug 25 to engage and mark a the side Thus line 3i between the lines 26 on the door edge 25 by drawing the gauge lengthwise along the door i2 as indicated by arrow 32 in Figure 4. A portion 33 of the body portion [5 extends beyond the side edge 19 and by engaging this extended portion 33 against the hinge edge 25 of the door the sharp ened edge of a lug 34 is spaced properly from the edge 25 to scribe a line (not shown) defining the depth of the cut to receive the hinge flap, see Figure 6. The door 12 is now gauged and marked, and is now ready to have the hinge flap recesses cut therein, Whichwill be properly located and of the determined length width anddepthl The gauge [3 is now positioned as in Figures 7 and 8'with the front edge [6 abutted against the outer edge 35 of the door stop strip 36, apart of the door frame H, and with the flanges 22 resting upon the hinge receiving surface iii of the frame II at the nicks I4. Lines 38 may now be scribed across the surface 31, see Figure '7, using the flanges 22 as guides for the scribing tool. The'amount the inner edge of the hinge flap sets away from the edge 35 of the stop strip 35 is now gauged and marked by engaging the side edge l8 against the strip edge 35, see Figures 9 and 10 so as to locate the sharpened edge of a lug 3e away from the strip edge 35 the proper amount. The gauge I3 is now drawn along the stopstrip edge 35 in the direction of arrow 4|, Figure 9, to cause the lug 39 to scribe a line 42between the lines 38. The amount the line 42 is spaced from the stop strip edge 35 is slightly more-than the amount the line 3i is spaced from the back surface of the door l2 to allow clearance when the door swings on the hinges. To obtain this difference in dimensions the flange 21 is spaced from the side edge "iii a slightly lesser amount than the lug 33 is spaced from the side edge l8, see Figures 5 and 10. The extended portion 33, of the gauge, is now laid upon the surface 31 with the lug 3d engaging the edge of the surface 31, -''see Figure 11 to scribe a line (not shown) defining the depth of the cut to receive the hinge flap. "The gauge i3 is preferably provided with a thickened rear portion 43 to facilitate holding it during the gauging and marking of the guide lines. This thickened portion may be formed by bending the rear portion of the plate I5 over and back'upon itself to form the hollow boxlikeportion 43. The shoulder 24 is assisted in its locating, or squaring, operation by the front end of the flange 2i which terminates at the shoulder 24, and a short flange 44 extending downwardly from the bottom of the plate in alignment with the shoulder 24 starting from the side edge IS.

The device of this invention is particularly useful and time saving in home building wherein the same size and style of hinges are used for all of the interior doors, and thus the dimensions to be gauged, and the outline of the hinge flap receiving cuts to be defined, will be the same. All gauging and marking means are conveniently arranged and associated in one unit which is substantially flat and light in weight and thus may be readily carried by the workman in a pocket. Having the various gauging and marking means permanently set in respect to the required dimensions for the hinge to be installed, no time and labor is required and lost in making adjustments.

While there has been shown and described herein a preferred form of the invention, it will be understood that the novel features and principles of this invention may be embodied in other specific forms without departing from the spiritand essential attributes thereof, and it is therefore desired that the present embodiment be considered in all respects as illustrative, and not restrictive, reference being had to the claims rather than to the foregoing description to indicate the scope of the invention.
